This figure, the Halo 3 Spartan Soldier Security (Steel) Action Figure, is a GameStop Exclusive, like all Steel Spartans. It has a Plasma Pistol, a SMG, and a Trip Mine. This figure has the most variety of accessories of all the Halo 3 figures.

This figure has an antenna on the back because it has Security armor. The antenna cannot be removed to be put on the back of another Spartan figure, unlike how all Halo 3 Spartans have interchangeable armor and weapons. Purchasing this figure gives you 10 Halo Points.
